To all whom it may concern:

' a citizen of the United States, residing at Youngstown, in the countyof Mahoning and State of Ohio, have invented certain new and usefulImprovements in Mechanical Recording-Scales, of which the following is aspecification, reference being had therein to the accompanyingdrawings,forming part of this specification, in which- Figure 1 is aview in front elevation of my improved registering-scale.

Figs. 13 and 14 are detail viewsshowing a modified construction of wheel-turning mechanism.

Fig. 15 is a detail view illustrating a modification.

My invention relates to an improvement I in scales; and it consists ofmeans whereby each operation of the scale is registered in conformitywith the weighing operation by means of one or more type-wheels whichprint the weight for each operation upon a tape which progressivelytravels through the machine and is thus provided with a record of all ofthe operations for an stated period. The printing-wheel is direct ycontrolled by the poise through a connection adapted to bring the propert position correspon in to the wei'g t indi cated by'the poise on t ebeam.

The invention also provides means for application to scales of differentcapacity by combining the poise's of a double beam-scale. with a doublewheel construction and also for automatically adjusting a supplementalprinting-wheel by the removal of the weights.

Referring now to the drawings, 2 is the cap of a scale provided with theusual balancinge-figures into rinting' beam3 and poise 4, the beam beingpreferably provided with a clearance-opening for the passage andprotection of the chain.- Mounted upon the cap 2 is an inclosing case 5,Within which is located the printing registering mechanism, the casebeing provided with a door or gate 6, adapted to be locked to preventunauthorized intrusion, it being desired to accumulate the recordedweights during any stated period, as a day, and to remove a portion ofthe'strip containing them at the termination of such period forexamination or filing.

Rotatabl mounted on a spindle or shaft 7, journale in bearings in asuitable frame 8 Within the case, is a Wheel 9,provided with a series ofprinting type-figures 10, arranged a partially or wholly around itsperiphery, the

wheel also being provided wi a groove 11 for actuating chain or cord12,whichis secured to the wheel at a point sufliciently far around itscircumference to insure suflicient rotation for the greatest range ofmovement of the poise 4. The chain 12 passes from wheel 9 downwardlyaround a guiding-sheave wheel 13, mounted in a suitable openin in thebeam, and is connected to the poise 4, as

shown, so that as the poise is moved out-' wardl -to theindicating-point on the beam it wil carry the chain with it, andthusanchor that end of the chain, so that when the wheel is' rotated, ashereinafter described, it will act to limit its movement at the properpoint for correct printing.

The mechanism is acuated by a key-lever- 14, pivoted at 15,provided witha de ressingterminal 16, extending outwardly t rou h a slot in the endof the case 5 and normally eld retracted inposition for operation by aspring.

17. A wheel-actuating arm 18 is pivotally 23 is a roll of paper taperotatably mount- I ed on bearin s 24, journaled in suitablesupporting-brac ets 25, the tape being arranged 1n alinement with thetype-wheel and adapted to be drawn successively from the roll asit isused.

The arm 14 is provided with a laterallyarranged inwardly extending tmpan 26, preferably rounded at its upper si e to insure good contact andto prevent contact with the adjacent non-registering type and providedwith slots 27 27, through which the tape is laced, as clearly shown inFig. 4, so as to present a limited section only of the tape a ainst thetype. The lever 14 is also provide with a locking pin or abutment 28,adapted to engage notches or grooves 29 around the edge of thetype-wheel and to fixedly adjust it to the exact position desired at themoment when the printing operation takesplace. The

type are inked b r a roller 30, mounted in a frame 31, pivota ly mountedon bearing-pin 15 or elsewhere and normally held in contact with thetype by spring 32.

The tape passes from the printing-tympan around a guiding pin or roller33, mounted in frame 31 or elsewhere, in a suitable position to lead thetape downwardly away from the type and then upwardly between aspringpressed feeding-roller 34 and a feeding-wheel 35, convenientlymadein the form of a ratchetwheel. The feeding-wheel 35 is rotatably mountedon a bearing pin or shaft 36, journaled in a suitable bracket 37 whilethe roller 34 is rotatably mounted on a pin or shaft 38, carried by ahousing 39, slidingly mounted upon supporting guiding extensions 40. Theroller 34 and the intervening tape are held into operative engagementwith feed-wheel 35 by springs 41, connecting shafts 36 and 38, orotherwise suitably applied, and the housing 39 is provided with a button42, by which it and the roller 34 are raised to free the ta e when it isdesired to draw it freely from t 1e machine for removal of a completedsection or series of printed numbers.

Feeding movement is imparted to the tape at each operation of lever 14 bmeans of a spring-pressed pawl 43, pivote at 44 in an arm 45, secured tothe hub or any suitable portion of the lever, as shown. The pawl passesdownwardly on downward movement of the lever, engaging one of theratchetteeth 46 of wheel 35 on upward movement due to spring 17 afterthe printing operation, thus shifting wheel 35 one space andcorrespondingly moving the tape forward sufficiently far for the nextoperation.

For the purpose of assisting in reversing the wheel 9 at the lastportion of its reverse travel, also bringing it to a constant initialposition, and to insureinking of all of the type and relieving the chain12 of strain, a counterweight 47 is suitably secured upon the wheel,although ordinarily the friction-arm 18 will impart reverse movement toit when the lever is retracted. A dash-pot 48 is connected at 49 tolever 14, adapted to engage a plunger-rod 50, pivoted at 51, which actsto revent a too sudden action of lever 14 and its connected parts.

It is desirable to give a signal when the. lever 14 has been depressedto its full limit, and thus insure. a complete operation, and for thispurpose I have provideda bell 52, which is sounded by a tapper 53,thrown into contact by the upper end of arm 18 at about the limit of itsupward travel, thus indicating to the operator the completion of a fulloperation. It is obvious that the bell or other similar signal may belocated at any suitable position in the apparatus and that it may .besounded by any convenient mechanism ada ted to be actuated by theoperative mec anism at the proper time, as stated.

The operation will be readily understood from the foregoing description.In the operation of weighing, the poise is located upon the beam, whichis preferably notched to prevent disturbance of the poise by the tensionof the wheel on the chain. -The movement of the type-wheel is thusregulated, so that the printing-figures corresponding to the indicatedweight will be arrested b the chain in properlocation for printing, anthe operation is completed by depressing the lever and then releasingit, the tape thus being imprinted with the recorded weight. Thesuccessively-recorded weights will be imprinted in alinement with eachother and may easily be added together to find the total weight for anyselected period after the tape has been torn off and removed.

The machine just described is adapted only to a scale having thecapacity indicated by the maximum capaeit graduated on the beamas, forinstance, our hundred pounds. When it is desired to apply the inventionto scales of larger capacity than can be graduated over the range of asingle beam, I employ the modifications shown in Figs. 9, 10, 11, and12. In the construction shown in Figs. 9 and 10 means are rovidedwhereby upon removal of the weig its 54 from their rack for use on theouter end of the beam movement proportionate to the width of the weightis imparted to a supplemental hundreds or thousands wheel 55 through aconnected pinion-wheel, en aged by a rack bar 56, normally retracted y as )ring 58 and normally held outwardly by t 1e weights or some of themwhen in position on the rack. As one or more weights are removed for usethe rack-bar will be proportionally retracted, rotating the pinion andty )e wheel to its proper position, said wheel t hen operating inconjunction with the units-wheel t). It will be understood thatotherwise the same mechanism is employed performing the same functions,it being only necessary to provide a sufliciently wide tape with acorresponding change in the other elements, the lever 14 being providedwith an additional arresting or adjusting pin 28 for the additionalwheel. This mechanism operates as follows: During the operation ofweighing and recording we will sup )ose the beam to be graduated over arange of one hundred pounds, each notch on the beam representing onepound, the. full ICS capacity of the scale being, say, six hundredpounds, the difference between one hundred and six hundred bein made upb the use of weights. In the we1 hin of a oad of, we will say, -fourhundre an sixty pounds the first 0 eration will be to remove fourhundred pound; in weights from the weightrack and to place them on thecounterpoise on the end of the beam. This will effect to allow the bar56, actuated b into the space whic was'previousl occupied by theseweights, and consequent y turn by the rack-and-gear movement thetype-wheel 54 to such a position as will make it print the figure 4 1nalinement with the number 60, which will be printed by type-wheel 9,controlled by the chain and brought to position by the oise and levermechanism when thelever is epressed for the purpose of makin a record.

In the modification shown in Figs. 11 and 12 a double beam is used, thelower bar 59 of which is traveled by a sufficiently heavy poise tobalance at its greatest movements over the full ca acity of the scale. Imerely provide a supp emental type-wheel 55, provided with figurescorres ending to the hundreds and thousands of earn 59, connected by achain 12, said wheel operating in conjunction with units-wheel 9 througha duplicate set of mechanism, the same in all respects as that alreadydescribed.

In Figs. 13 and 14 is shown a modified arrangement of the frictionmechanism by which the type wheel or wheels are brought to the properposition for rinting on depression of the key-lever 14. In place of therubber hub. 21, fixed to wheel 9 or its shaft, a pinion is engragedby arack-bar 61, corresponding to iction-arm 18. The pinion 60 is loose onthe wheel-shaft 62 and is provided with a spider or star wheel 63, thearms of which bear with considerable friction against a washer 64, ofleather,rubber, or other frictional material, secured to the side of thetypewheel.

In Fig. 15 I have shown a detail view illustrating a modifiedconstruction of connection between the poise-chain and the poise,employing a terminal wedge, adapted to be drawn forward by the chainbetween the 0ppositely-dis osed arms 65 65 of the oise and to expand tem a ainst the inner si es of the slotted beam. T 's construction isdesigned as a substitute for a notched beam and operates to clamp thepoise in osition, its bmding hold inereasing, so that it will thus beheld rigidly in position against disturbance by the printing operation.

The advantages of my invention will be readily appreciated from theforegoing description, and it will be found to perform itsfunctions in asatisfactory and efficient manner. The mechanism is com arativelysimple, not liable to get out of or er, and the rethe spring 57, to movesults secured are hi hly desirable and render the accurac of weiiinweights in ependent of the operator and therefore not subject to mist'akChan es and variations may be made by the skilled mechanic in thevarious parts or details of construction; but all such are to beconsidered as within the scope of the following claims.
